The thread must be known to the VM as otherwise you wouldn't have a 
JNIEnv and wouldn't be able to call the method (so I'll bet the thread 
is attaching via AttachCurrentThread somewhere).

As to the ArrayIndexOutOfBoundsException, that does seem to be a bug as 
I assume that getClassContext is returning an array of one element 
corresponding to the caller frame (getBundle in this case).
